Enchat: Secured & Realtime Messaging Android Application

Abstract

Humans have made a lot of progress in terms of science and technology. With the advancement of science and technology, many improvements have been made in the communication system. Nowadays, messaging apps are one of the most important means of communication. Using messaging apps has made people's communication easier. We have built our app to facilitate human communication and to provide various facilities for communication. People will benefit from using our app to communicate with each other easily. This app built by us is completely free and ad-free. In this app, users can open accounts and communicate with each other using their mobile numbers. In addition to messaging without interruption, users can make calls as needed. Using it, users can open groups for group-based communication, and many people can communicate simultaneously. Users can share photos, videos, and documents with the same app as they need. Security is very important when it comes to communicating through messaging apps. We have worked on the security of the users in the app. We have provided a secret chat option in this app through which users can communicate with each other while maintaining privacy. We have worked to protect users from shoulder surfing issues. Through shoulder surfing, others can see users' personal information and use the information to harm users. We came up with an idea in the field of messaging to solve this problem. While messaging using our mobile app, the user must tap on the message sent by the user to decrypt the message before viewing the message. After some time after decrypting the message, it will automatically be encrypted again. As a result of this process, users can avoid shoulder surfing. Moreover, users can report any problem to the authorities through feedback.
